A method for detecting air leak when using a double-lumen endobronchial tube is described. The ventilatory circuit is directly attached to the lumen of the ventilated lung. A balloon is fitted snugly over the open lumen of the tube to the nonventilated lung. If lung separation is incomplete, the balloon will inflate with each ventilation.
